Awesome. I can't work on this right now but I'm glad the real experts have taken on the issue.

Real experts would have included a perfect solution for arguments at or close to the Gamma minimum. ;-) There was a similar problem when Lambert's W was implemented in XROM, but back then I could provide a solution. Let's see if the community can come up with something similar here.

Test cases:
Code:
   0,88560 31944 10888 70027 88159 00582 5887 => error    0,88560 31944 10888 70027 88159 00582 5888 =>  1,4616 32144 96836 23537 47806 24573 3288

Otherwise it's not perfect. ;-)
